Revert "kvmclock: set scheduler clock stable"



This reverts commit ff7bbb9c.
Sasha Levin is seeing odd jump in time values during boot of a KVM guest:

[...]
[    0.000000] tsc: Detected 2260.998 MHz processor
[3376355.247558] Calibrating delay loop (skipped) preset value..
[...]

and bisected them to this commit.
